Tibrina Hobson/WireImage(LOS ANGELES) -- Looks like no wedding bells for Whitney Houston’s daughter Bobbi Kristina Brown and Nick Gordon. The pair have long kept people guessing about the status of their relationship, but recently Gordon seemed to make it clear that they are just friends.

“@REALbkBrown and I are not engaged or dating. Just close like we have always been,” he tweeted Nov. 18.

Brown also hinted that any romance was over in a series of cryptic tweets.

“Who do I trust in this world? Pfft well that’s easy beezie, #Myself,” she wrote Nov. 26.

“I guess it’s time 4me2stop depending on anymore. It’s my time2follow what Mom&The Lord put out on this path for me. #Thankful. Mom xxo,” she wrote a day later.

Brown, 19, and her 22-year-old adopted brother have denied engagement rumors since she began sporting her mother’s large sapphire on her left hand. But they haven’t been exactly shy about showing their affection for each other in public and in photos posted on their Twitter accounts.

In October, they announced their “engagement” during a sneak peek of their reality show, The Houstons: On Our Own.

But Brown’s aunt, Pat Houston told ABC News in October that the pair have nothing more than a “very, very strong friendship. Very strong.”

“A lot of teenagers, when they hit 18, they think they’re grown,” Houston said. “They think they know it all, they think they know about relationships. You just have to be there to navigate and guide them.”

It’s been a challenging week for the late singer’s daughter. Just before noon Wednesday, she wrecked her Camaro after losing control of the car and driving down an embankment. Brown crashed into several small trees before the car came to a stop on a public trail.

“She lost control of her vehicle due to speed,” George Gordon, a spokesman for the Alpharetta, Ga., Department of Public Safety told ABC News, adding that drugs or alcohol don’t appear to be involved.

Brown, who was uninjured, was cited for failure to maintain lane and issued a court date.
